The mechanism demonstrates the relationship between the ratio of the number of teeth on spur gears and the transmission ratio of gears. With straightforward experiments, the torque conversion in gear wheel pairs and the efficiency of a gear unit are investigated. The model is intended for wall mounting. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
